Make each into improper fraction
2 x 8 + 5. = 21 / 8
3(10) + 2 = 32/3
21/8(32/3) = ((21x32)/(8x3) reduce by 3/3
(7x32)/(8) reduce by 8/8
7x4 = 28
1. -0.6, 2. 0.73, 3. 0.72 those are my answer
To find the volume you will multiply the length by the width by the height (V=lwh).
V = 9 x 3 1/4 x 2/3
V = 19 1/2 cubic inches.
To find the volume of any prism, you find the area of the base (length times width in this case) and then multiply it by the height.
